Each end oi the tie is oi similar or hire formation, hence one end oniy is shown in the accompanying drawings end described st icngthhereinafter. in some instances 6c the tie may be of sccionol fcrnmtion, the sections being jointed about as shown in Fig 4, one section having it tapered tongue} and the instill rec-Lion having a. correspondingly tapered recess 2 in which the tongue 1 is iit: ted and secured by means of 2. p111 3 throne-h registering openings in the overlapped parts comprising the joint. The tongue 1 he" e 'c m. mi curved'pori? :4, a. hp 5 end an intermediate straight portions. 1c The recess 2 has its inner wall oi a. shape corresponding to the extremity of the tongue 1. The shoulders st the base of the tongue 1 are siightly curved and extrcinitios'of t. e parts bordering upon the recess 2 are oorre- 7 5 spondingiy curved to make :1- close lOlli o'. The joint between the sections such as to admit of s. iiinited do only of the sections so that they may accommodate themselves to roiling stock when the tic placed upon. a rosdbed of earth. ii-sen the roodbed is of metal or wood, soul es nits from building a railway across :1- trestle, bridge or. other structure, the cross tie will be of solid formation, that is free from joints. To pro-rent cndwise or istersl increment oi the tie, the some is provided with pendent flanges 7 which are notched or serr-e ed in. their lower edges to iorni a. of projections, which become embedded in the surface of the road so ii depression is provided no i the the tie and extends transversel (her is designed to lG-C'GIVB a fibrous bio'i U; the latter being prefcrshiy of wood and titted iii the deoression which for 15ft sent therefor and projecting a short distance shove the top surface of ti'io tie to receive the r U which. is pieced thereoi'ii ihcblock)" with its fii this being 'iho-piirposc'oi shc'iioro s h; P vibrationsend pie weer upon the rolling die} of or may he formed 'directlfii'i the User f ncd'in the tie. in the event of the depi seat being formed. in s choir i1 theistic openings .14 do not extend through the bot-v held in the opening-of. the tie by pins or fastening's 12 passed through openings formed in thesides of the tie and enter' openings formedgin the sides of pendent portions of the chair. The rail .10 is held to the tie by means of keys 13,, thelatter being passed through vertical openin s 14 forme in the .tie at 0 posite sides of t e depression or seat 8. v T e tom of the tie, but'in order' to provide for escape of water,:dirt: or the like, clearance openings 15 lead from the lower endsof the tion when assembling-the arts, shimpieces v o enin'gs-14,are retaine '18 are provided and are p aced between the lower ends of the recesses 16 and the pins 17..

The shim pieces 18 vary in thickness in order to allow for different spaces between the pins .17 and the lower ends of the recesses 16 after the parts have been assembled. Theshim pieces 18 are held to the keys 13' by positive mt'erlocking means. For this urpose. a dove-tailgr'oove 19is formed in t e recessed l portion 16' of each key and the shim pieces are provided with dove-tail projections 20 of a size to snugly fit the d ove-tail groove 19. Thegroove 19 is closed at it's-lower end-and opensat its upper end through the outer sides of the key. As a result of this/ construction, the shim pieces are retained in place at'the lower endsof the recesses 16.. The keys 13, when slipped into the vertical lnplace bymeans of t e pins 17 Which-pass through transverse o enmgs 21 formed in the tie and engage with t e shoulders formed at the lower ends of the recesses 16; The pins 17 are formed near one to enter the recesses 23. The entrance ends of the openings 21 are enlarged to admit of end with bits 22 which are adapted to enter recesses 23 in communication with the openings 21 thereby preventing displacement of the pins .17 when inserted inthe openings 21 and given a partial turn to cause the bits 22 the introduction 'of a key 24 when it is required to remove the pins ,17, said key 24' having a spring actuated catch 25' to make engagement with the pin 17 to admit of removing the latter from its opening. A notch 26' extends from the enlarged end of the openin 21 to admit of the passage of the bit 22, eit. or when placing the pin 17 in the opening21 or when removing it from said opening. The notch 26 is closed by means of a block 27, thereby preventing the entrance of foreign matter into the recess 23. The notch newer 26 extends vertically a short distance to ad- Init of a suitable instrument being engaged with the block 27 when it is the same upward to permit of the-passage of the bit 22. The notch 26 and the entrance end of the opening 21 are closed by means of a cover 28 which is pivoted at its upper end to normally hang loosely and close the said notch and opening. An opening29 leads horizontally outward from the bottom of the re 'ces s 23' to' carry off. water and a mit of the v 'discharge'of any dust or foreign atter that mayfindits W837 into the recess 23. Lugs 30 project vertica y from the. tie and are a aptedto en' agelthe upper ends of the keys 13,

required to move thereby racing the-same against any lateral strain that'may come upon the rails. These lugs also form fulcra-for a crowbar or other tioni'ito enable the withdrawal of the v eys from-their openings 14, should they become bound therelnfrom any cause. A series of 11017011633 1 are formed in the upper rear'sides pf the keys'to receive the end or point of the crowbar when using the latter to pry the keys implement that may be brought into re uisiout of the openings 14. In the event of the tie being provided with a series of depressions" or seats 8 to receive fibrous blocks 9, two or i more keys may be secured in place by means of a sin" is pin 17, the latter engaging with recesses lormed in the outer sides of proximal keys.

The block may be of any material desired and may be of steel or other metal or a combination thereof with wood. It should bemade to roject above the tie a short d-is-- tance an may comprise ,a number of 'ieces, thelbottom which ma e filled w1th a wooden black, sand or o't ermaterial. r This steel or metal block should not extend more than about iece-havingaspace the ebelow two-eighths of an inch over the top of. the 1 chairs or seat Where therail is indicated on the tie. The combination of a steel or metal cross tie with twoprincipal-blocks madeof different materials and two principal keys'as locking one another and the couphng thereof, is advantageous, as will be readily understood. Having thus described the invention, what is claimed as new is:

1. A tie having an approximately vertical opening and a horizontal opening, a key fitted into the vertical opening and havin a recess in one side, a pin passed through t e transverse opening of the tie and having a fii'rtion entering t e recess of the key, and a shim interposed between said pin and the lower end of the recess formed in the side of the key. 2:"In combination, a tie having an approximately vertical opening and a horizontal.

ppcnmg, a key fitted into the vertical opens...

tie and having a portion projected into the recess of the key, a slum interposed between the pin and lower end of the recess of' the key,- and interlocking means between said key and shim.

3. In combination, a railway tie having a vertical opening and a horizontal opening, the latter provided near its entrance end with a recess, a key fitted into the vertical opening, and a pin passed through said horizontal opening and engaging with the key to retain the same in place and provided near its outer end with a bit toenter the said recess.

4. In combination, a railway tie having a vertical opening and a horizontal opening, the latter provided near one end with a recess, a key fitted into the vertical opening, a pin passed through said horizontal opening and engaging with the key to retain the same in place and provided with a bit to enter the said recess noar one end of the-horizontal opening, and a block arranged within the tie at one side of said horizontal opening to close the entrance to said recess to exclude forei matter after the parts havebeen placed 1n position.

5. In combination, a tie having a vertical opening, and a horizontal opening, the latter provided near one end with a recess and with a notch forming an entrance to said recess, a key fitted into the vertical opening, a pin fitted in-the horizontal opening and having a bit to ass through theaforesaid notch and enter the said recess, and a .block arranged within said notch and normally closing the entrance to said recess.

In'testimony whereof I afiix my signature in presence of two Witnesses.
